Summary

Metroxylon amicarum (amicarium Latin – 'of friends' also known as the Caroline ivory-nut palm) is a species of flowering plant in the family Arecaceae, endemic to the Caroline Islands. It was named for the Friendly Islands, now Tonga, from where it was first thought to have descended. It is the only species in the Metroxylon genus which is not hapaxanthic.

Cultivation

Nothing derived: no habitat climate for this species.

Climate across the habitat

No habitat climate can be derived: Only 2 distinct land cells of the climate grid hold an in-range record placed to within 10 km; three are needed for an envelope. 6 of the 8 in-range records are placed to worse than 10 km, or to no stated accuracy and fewer than three decimals or by something other than a person's observation, and cannot place a climate cell, though they count for the map and its marker.

Natural habitat

Native range as published by WCVP; the marker is where the records are densest and decides nothing.

Openly licensed records inside the range, framed on where they fall.

Evidence usedThe map marker rests on all 8 georeferenced records inside the native range, all openly licensed and shown on the map. 6 records outside the WCVP native range not used. Under a dozen records behind the map. No climate across the range is derived for this species. 6 in-range records are placed to worse than 10 km, or with no stated accuracy (admitted only as a person's observation to three decimals), and stay on the map but off the climate.

How this section is made

The map marker: the openly licensed record nearest the middle of the densest 1° population of the 8 in-range records; it decides nothing. Records outside the native range, living specimens and records marked introduced are not used; which records count.

Every source is recorded as having answered, reported nothing, refused, failed, not been asked, or answered twice where one answer is taken (“not taken: two items answered”), and, for a source asked when this page was built, when: the figures are as the source held them that day; a source read from a file (Kew's World Checklist, a GBIF download) says "as of" the file's day instead; a row carried from an earlier build of the page names that build instead. Only “nothing to report” is ever shown as an absence. Records came from 7 datasets via GBIF.org; each carries its own licence.
